Pro-7 Manual Profoto, Stockholm, Sweden. Safety Instructions

Profoto generators and ﬂash heads are part of a complete professional lighting system. Please read the instruction manual carefully before use. Flash tubes and modelling lights emit considerable heat and can be dangerous if not used properly. Always unplug the lamp cable from the generator before changing modelling light, glass cover or ﬂash tube. Under no circumstances are generators or heads to be opened! There is high voltage inside the generator! Service is only to be carried out by authorised personnel.

. Never connect accessories of other brands without consulting an authorised service station. . Do not touch hot glass or metal parts. . Do not obstruct ventilation. . Do not connect the lamp head with the transport cap in place. . Never place ﬁlters or diffusing material directly onto glass covers, ﬂash tubes or modelling lights.

. Never position the light extremely close to people. . When mounting umbrellas, do not touch ﬂash tubes or modelling lights with the metal shaft – risk of high voltage.

. Always use a grounded power supply/mains outlet. . Protect the ﬂash equipment against moisture, condensation, heat, sand and dirt. Contents

3 Thanks!

Thanks for showing us your conﬁdence by investing in a Profoto Pro-7 system. For more than three decades we have sought the perfect light. What pushes us is the convic- tion that we can even offer the most demanding photographer yet better tools. Still we know that we will never be able to offer the best light there is; the natural sunlight. But Pro-7 comes very close. It is the best series we have ever manufactured.

Before our products are shipped we have them pass an extensive and strict testing program. We check that they pass the quality and capacity levels the most demanding photographers require. For this reason our flash equipment is the standard in most rental studios in New York and Tokyo and the most rented flash all over the world. The system consists of different generators built and designed to meet the demands of the most demanding photographers on this planet. Yet the most important thing is the light you create and it is then essential that the system offers freedom to create your own light. The Pro-7 heads offer you this possibility in particular. The light source, both the flash tube and the modelling light, is placed high and free in the flash head. This makes it easier for you to adjust the light and use your creativity. The reflectors are moveable and lock easily into place. You can move the source of light toward the focus of the reflector to reflect the light backwards before it is projected forward. This is not new, of course. Our flash heads have always been designed that way. What is new, however, is our new glass cover, which is designed to increase precision. The Pro-7 head and the Pro-7 twin are supplied with a frosted and UV-coated cover glass, which together with the flash tube, produces a colour temperature adapted to daylight colour film. There are glass covers with varying filtration, for greater changes.

The whole Pro-7 system is modular. Every single reﬂector and accessory creates its spe- cial light and the unique Profoto focusing system offers you a possibility to create your own light with only a few different reﬂectors.

4 Profotos founders Eckhard Heine och Conny Dufgran, At ”Photokina”, Cologne, Germany 1968

”A photographer’s tools are a natural part of the creative process. Like a painter’s brush, an artist’s chisel or a musician’s instrument, their form and design should reﬂect their function, they should have the right feel, and they should be aesthetically pleasing”.

The modelling light is turned on and off with the black switch [1] at the back of the head. The built-in fan can easily be switched between continuous and thermostat-controlled operations [2]. Please note that when changing modelling light, flash tube or glass cover the lamp cable must be disconnected from the generator. The modelling light has a mini-can socket (E11). The flash tube has two metal pins. When removing a flash tube, pull it straight out of the sockets. When inserting a new flash tube, check that the trigger-wire clasps properly around the flash tube (please see mounting instructions in package). When mounting the glass cover, check that both locking springs connect properly into glass cover holes. In case the head overheats the modelling light automatically switches off. When the temperature has dropped sufficiently the modelling

8 Pro-7b head

The Pro-7b head is a small and easily transportable ﬂash

head exclusively designed for the Pro-7b generator. Please ProHead Pro-7b head note that when changing modelling light, flash tube or glass cover the lamp cable must be disconnected from the generator. The modelling light is a standard 100W lamp with an E11 socket. The flash tube has two pins. When removing a flash tube, pull it straight out of the sockets. When inserting a new flash tube, check that the trigger-wire clasps properly around the flash tube (please see mounting instructions in package). The head has no fan. Because of the heat generat- ed there is a certain limitation to the number of flashes per minute. At the back of the head there is an opening for attaching accessories like filters and barn doors.

9 ProTwin

The ProTwin is used to obtain extremely short flash duration, very quick recycling or to get 4800 Ws out of one single head. There are two flash tubes in a ProTwin. As the flash duration is shorter at low power settings, and as only half of the desired power is used in each tube, consequently shorter flash duration is obtained. For example if you need 1200 Ws, you fire 600 Ws from each tube, and your flash duration is shorter than if a standard ProHead is used. The flash duration at 1200 Ws with a ProHead is 1/2200 while it is only 1/3200 with a ProTwin. One or two generators can be used. If, on the contrary, you require 4800Ws from one head you connect ProTwin to two Pro-7/2400 generators. For the same reason shorter recycling times is obtained when two generators are used, as the recycling is faster when the generators in fact only need to recharge half the energy. Flash duration and recycling for a ProTwin at a certain power setting - for example 1200 Ws - compares with a ProHead set at 600 Ws. The modelling light is turned on and off with the black switch 1 [1] at the back of the head. The fan is controlled by a built-in 2 thermostat, which can be disconnected with the blue switch [2] after which the fan operates continuously. Please note that when changing modelling light, flash tube

11 Pro-7 ring

The ring flash fits all Pro-7 generators, and is an entirely mobile source of light. The interior diameter of 100 mm provides plenty of space for professional camera lenses. Since the camera holder can be tilted forward and backwards, as well as upwards and downwards, most cameras can be attached. This makes an excellent source of light in cramped areas, such as the interior of an automobile. Many fashion photographers also use the ring flash to find new angles and capture details. The ring flash provides a very distinct, directed light, but can be complemented by a soft light reflector, which increases the light source, thereby produc- ing a softer light with fewer sharp shadows. For close-ups, there is a reflector that focuses the light 50 cm in front of the camera lens. The maximum charge is 9600 Ws per minute. This means 4 flashes a minute at 2400 Ws, 8 flashes at 1200 Ws, 16 flashes at 600 Ws, etc. Changing flash tube is only to be done at a professional service station. Mounting the reflector • Remove the two ridged screws fixating the camera holder. • Remove the four ridged nuts holding the outer and inner reflectors together. • Run the lamp cable through the outer reflector and let the reflector slide into position. • Reassemble the outer and inner reflectors using the ridged nuts. • Reassemble the camera holder using the two ridged screws.

• Choose fast recharging by pressing the button [13] FAST

• For extra fast recharging choose the button [14] TURBO

Mains (AC) Connection Use the included power cable to connect at [1]. The Pro-7 can be connected to all common mains voltages 90 - 240 Volt, 50-60 Hz. The generator automatically senses which voltage range is supplied. The green lamp below the handle indicates that the generator is receiving power from the mains. If not check the mains fuse for faults. (Please also see ”Gas Generator” on page 24). Warning: Never use ordinary household extension cords to elongate the power cable. Connecting Lamp heads One, two or three lamp heads can be connected to the sockets marked A, B1 and B2 [2]. When connecting the lamp head plug, align the white dots on the plug with the white dot on the generator panel. Secure by turning the locking ring on the plug clockwise.

PLEASE NOTE! The energy output is determined by the energy dials A and B. The energy output will remain consistent, regardless of which lamp sockets are used or the number of lamp heads connected to them. Energy dumping is not necessary as long as the dial MASTER is turned to MAX. Energy Control The generator’s total energy is regulated with the control MASTER (6). The total energy can be adjusted in 1/6 f:stop increments from MAX down to minus 8/6 f:stops equivalent to 1 1/3 f:stops. When reducing the energy a ﬂash has to be released with the white push-button [11]. Then the chosen energy is obtained. Please also see ”Manual Bracketing” (page 20), ”Autobracket- ing” (page 20) and ”Colour Temperature” (page 23). Choice of Modelling Light The control [15] MOD. LIGHT is used to choose the following alternatives: • OFF Modelling light off • 1/1 Modelling light is receiving the designated proportional full energy determined by the positions of dials A, B & MASTER • 1/2 Modelling light is receiving the designated proportional half energy determined by the positions of dials A, B & MASTER • MAX Modelling light is at maximum, regardless of energy settings Half proportional modelling light is chosen when a Pro-7a/1200 and a Pro-7a/2400 are used together. To keep the modelling light proportionally aligned between the two generators, the Pro-7a/1200 is set to a 1/2 modelling light position, as the flash energy is half of the Pro-7a/2400.

18 [11] [13] [14]

Connecting Camera and Flash Meter The two sync sockets [9] allow the camera and ﬂash meter to be connected simultaneously. The 5 meter sync cord can without restrictions be elongated with a sync extension cable. Con- [15] necting generators can be done by means of the Profoto sync interconnection cord or by so called ”hard wiring”. Pro-7a 1200/2400 Recharging The recharging starts when the push-button [4] is activated. Slow, fast or turbo recharge can be chosen. When the two push-buttons [13] FAST and (14) TURBO are released, the generator will recharge slowly. Choose this alternative when the generator is connected to a mains supply with weak fuses, or if you are uncertain as to how well the mains supply is fused. This is also the case when weak gas generators are used for recharging (please see ”Gas Generator” page 24). With the button [13] FAST activated normal recharging is obtained. This is sufficient for most kinds of photography. The recharging time is 1.1 sec at 1200 Ws and 2.2 sec at 2400 Ws (230 V). When extremely short recharging times are required, as in fashion and sports photography, or when a motor-drive camera is used press the TURBO [14] button. The generator will now recharge extremely fast, in 0.7 sec at 1200 Ws and in 1.4 sec at 2400 Ws. You may blow the mains fuse and consequently this procedure can only take place for a short period of time.

19 [6] [8] [10]

Photocell The built-in photocell [8] will sense flash release as well as IR-signals from most IR-transmitters. The photocell is disabled when the button [10] SLAVE is released. Bracketing Manual exposure variations are performed as follows: • Point the MASTER control [6] at the arrow and release an ”open” flash by pressing the test button [11]. • Set the lighting as you would normally do, determine the appropriate f:stop and shoot the first frame. • Turn the MASTER control to the desired over-exposure: 1/6 - 4/6 of a f:stop and shoot the second frame. • Turn the MASTER control to the desired under-exposure: 1/6 - 4/6 of a f:stop. Release an ”open” flash by pressing the test button [11] and then shoot the third frame Autobracketing Exposure variations can also be obtained in an automatic way as follows: • Point the MASTER control [6] at the arrow and release an ”open” flash by pressing the test button [11]. • Set the lighting as you would normally do and determine the appropriate f:stop. • Turn the control to the desired f:stop 1/3, 1/2 or 2/3 • Start the autobracketing procedure by pressing the test button [11] releasing an ”open” flash. • The generator will now recharge for a ”normal” exposure, which is indicated by the test button [11] now flashing ”normally” i. e. equal intervals of light and ”no” light • Shoot the first frame

20 [11] [14]

• The generator will now recharge for an overexposed frame, which is indicated by the ready lamp lighting up for longer periods. • Shoot the second frame • The generator will now recharge for an underexposed frame, which is indicated by the ready lamp lighting up for shorter periods • Shoot the third frame

• The generator will now recharge for a normal exposure, and so on. Pro-7a 1200/2400 Turn the MASTER control towards the arrow each time new light readings are made. When more than one generator is involved in autobracketing and all generators have been set up and prepared, the sequence is initiated by pressing the ready lamp button of the generator where the sync cord is connected. If unsynchronised flashing occurs on any generator, adjust by first disconnecting the lamp cable and then press the ready lamp until the ”right” blinking rhythm is obtained. Automatic Safety Functions If the generator overheats for any reason a protective system will automatically start up. The generator’s recharging intervals will slow down and eventually the recharging will stop completely. After a while, when the temperature has decreased sufficiently, the generator will start recharging at a normal pace. This automatic protection will only start up under extreme conditions when the air vents are blocked for some reason. Due to the fast recharging, in TURBO [14] mode, at ”exceptional” recharging speed (energy turnover) sensitive parts of the equipment, such as the flash tubes are protected, by lengthening the recharging time.

Signals, Visible & Audible The green indicator [3] below the handle will light up when the generator is connected to the mains supply. The white ready lamp button [11] will light up when the generator is fully charged. The characteristics of the light vary (please see ”Autobracketing” page 20). When the generator is fully charged a short ”beep” can be heard. Releasing the button [12] marked SOUND can turn off this signal. The red indicator [16] will light up and the ”beep” will sound if the energy dial A [5] is in the A ONLY area and the dial B is not pointed towards the red indicator. Point dial B towards the red indicator and the ”beep” will disappear. If a flash is released before the generator is fully charged a long ”beep” will sound, indicating an underexposed frame. Reliability Testing - The R-Test The Profoto R-test guarantees that all products leaving the factory meet the very high stan- dards required of professional equipment by professional photographers. The R-test is a rigorous performance test that Profoto generators are put through - 720 full power flashes are released during one hour, which is equivalent to 20 rolls of 35 mm film. After the test the equipment is examined to see that all parts have kept a normal operating temperature and are not malfunctioning in any way. All Profoto products are subjected to the R-test prior to being shipped.

22 [11] [12] [16]

Colour Temperature The Pro-7 generators are perfectly suited for critical analouge (film) and digital shoots. The colour temperature is constant and reliable regardless of the energy output chosen with the dials A, B1 & B2. The colour temperature can be adjusted with the MASTER control [6]. Each 1/6 increment reduces the colour temperature by 50° Kelvin, which means a total down- scale of 400° Kelvin. Pro-7a 1200/2400 PLEASE NOTE: combining flash tubes and/or glass covers with different coatings can make even more distinctive colour temperature adjustments. Flash Duration The flash duration can be shortened by reducing the energy output with the dials A and B. The shortest flash duration using a Pro-7 head and a Pro-7a/1200 generator at 1/16 energy is 1/12000 sec. Lamp Heads The following are suited for Pro-7a 1200/2400: ProHead [90.07.09] Pro-7 ring [30.05.15] ProTwin [90.07.19] You can also use the Pro-7 head and the Pro-7 twin head.

Connecting Lamp Heads One or two lamp heads can be connected to the lamps head sockets [2]. When connecting the lamp head plug, align the dots on the plug with the white dot on the generator panel. Secure by turning the locking ring on the plug clockwise. Energy Control The energy output is regulated with the control ENERGY [5]. The energy can be adjusted in 1/6 f:stop increments, from 1/1 down to 1/32 of the total energy (equivalent to six f:stops). At any change of the energy output the white ready lamp [9] will start ﬂashing indicating that the energy needs to be dumped i. e. by pushing the test button [9]. The generator will thereafter be charged to the chosen energy output. Choice of Modelling Light The control marked MOD.LIGHT [12] is used to choose the following alternatives: OFF Modelling light is turned off 1/1 Modelling light is receiving the designated proportional energy at full intensity determined by the position of the ENERGY control [5] 1/2 Modelling light* is receiving the designated proportional energy at half the intensity determined by the position of the ENERGY control [5]. MAX Modelling light is at maximum light output regardless of energy setting When connecting two lamp heads or a ProTwin the modelling light proportionality is automatically adjusted.

* The alternative 1/2 proportional modelling light is chosen in those cases when a Pro-7/1200 and a Pro-7/2400 are used

together. To obtain the exact proportionality between the two generators the Pro-7/1200 modelling light has to be set at

1/2, as the ﬂash energy is half of the Pro-7/2400.

Photocell The built-in photocell [6] will sense flash release as well as IR-signals from most IR-transmitters. The photocell is disabled when the button marked SLAVE [8] is released. Signals, Audible & Visible The green indicator [3] below the handle will light up once the generator is connected to the mains outlet. The white ready lamp [9] will light up when the generator is fully charged. The button will not light up when the modelling light control [12] is in the OFF position. At the first initial charge, when the generator is connected to the mains supply, or when the energy output has been changed the white ready lamp [9] will flash. Dumping the energy is then required. At the next recharging the lamp will light up with a constant light. A short ”beep” can be heard when the generator is fully recharged. Releasing the button marked SOUND [10] will turn off this signal. If a flash is fired before the generator is fully charged a long ”beep” can be heard thus indicating an underexposed frame. Safety Functions After having connected the generator to the mains outlet the first charge is always made to maximum energy for capacitor formation. This is important in order to avoid damage after leaving the generator unused for some time. If the generator for any reason whatsoever overheats, the recharging will stop completely. After a while, when the temperature has gone down sufficiently, the generator will start recharging at a normal pace again. This automatic protection system will only start up under extreme conditions, for instance when the air vents are blocked for some reason.

PLEASE NOTE: The air vents of the generator must never be blocked or covered in any way. Never store your flash equipment in a car on a hot and sunny day. Never use a generator that is placed inside a case or transport box. Avoid storing the generator close or below the freezing point, which can lead to loss of capacity (flash output) and risk of condensation when used in a warmer surrounding immediately. Do not expose any flash equipment to wet or humid environments or extreme electro-magnetic fields. 30 guaranteed forthree months. glass covers,modelling lampsandbatteries.Products purchasedfor rentalpurposesare All Profoto productsare guaranteedforaperiodoftwoyearswiththeexceptionflash tubes, W Y P The followingaresuitedforPro-7s 1200/2400: L achieved withaPro-7s/1200 unit. see ”Technical Data”onpage32).IfaPro-7 twinisusedaflashdurationof1/12000canbe P R Flash Duration even moredistinctivecolourtemperatureadjustments.

Changing Battery By putting the two handles at the bottom together the battery cassette is released and the battery can easily be pulled out. A new battery is pushed all the way into the generator and is locked by directing the handles away from each other. When changing the battery it must be mounted in a battery cassette by an authorised service station. If the battery is not purchased at Profoto a Hitachi HV 12 -12 unit must be used. Connecting Lamp Heads One or two lamp heads can be connected to the lamp head sockets A & B [1]. When connecting the lamp head plug, align the dots on the plug with the white dot on the generator panel. Secure by turning the locking ring on the plug clockwise. Energy Control The energy output is regulated over seven f:stops. The energy can partly be adjusted with the control MASTER [13] in 1/6 f:stop increments, from 1/1 down to 1/16 of the total energy (equivalent to ﬁve f:stops) partly with the SYM/ASYM switch [2] through one or two lamp heads. One lamp head: The total energy chosen is obtained if the lamp head is connected to A and the SYM/ASYM switch is at A 1/1(1/2), B 1/2. The lamp head can be connected to socket A or B. If the lamp head is connected to A the total energy is obtained chosen with the control MASTER [13]. If the lamp

Recharging The recharging starts when the ON/OFF switch [12] is pushed down. Slow or fast recharging can be chosen. When the button FAST [10] is released, the generator will recharge slowly. Push the FAST button [10] for normal recharging cycles; this is sufficient for most kinds of photography. The recharging time is approx. 2.8 sec at full energy. When extremely short recharging times are required, for instance when operating a motor-drive camera, choose lower energy settings. The lowest energy setting offers the fastest recharging rate (0.18 sec). The generator is turned off by pressing the button ON [12] for a minimum of three seconds. The generator automatically turns off when the controls MASTER [13], MOD.LIGHT [11] and the sync outlets have not been in use for 30 minutes. Photocell The built-in photocell [5] will sense flash release as well as IR-signals from most IR-transmitters. The photocell is disabled when the button marked SLAVE [7] is released. The photocell can also, via cable, trigger off an additional generator. Signals, Audible & Visible One of the indicator lights for the battery charge [3] will light up once the generator is turned on. The charge indicator [3] is up-dated when the generator is turned on or when a flash is fired. When all lights light up the generator has no charging value - fire a flash. When the energy output is changed the white ready lamp [8] turns off thus indicating that dumping of the energy is in progress. A short ”beep” can be heard when the generator is fully recharged. Releasing the button SOUND [9] can turn off this signal. The generator can be restarted directly from a camera, if a sync cord is connected, by shooting a frame. If a flash is fired before the generator is fully charged a long ”beep” can be heard thus indicating an underexposed frame. A number of short consecutive ”beeps” - 16 - can be heard before the generator automatically turns itself off. 38 R-test priortobeing shipped. temperature and arenotmalfunctioninginanyway.

Colour Temperature The Pro-7 generators are perfectly suited for critical analouge (film) and digital shoots. The colour temperature is constant with a variation of a maximum of +/- 150° Kelvin. PLEASE NOTE: combining flash tubes and/or glass covers with different coatings can make even more distinctive colour temperature adjustments. Flash Duration Reducing the energy output with the control MASTER [13] shortens the flash duration. The shortest flash duration using a Pro-7 head is 1/3000 sec. (For more details please see ”Technical Data” on page 41). Lamp Heads The ProHead, ProTwin, Pro-7 head, the Pro-7 twin, the Pro-7 ring or the exclusively designed Pro-7b head can be used. With the ProTwin and two Pro-7b generators 2400 Ws can be obtained. Warranty All Profoto products are guaranteed for a period of two years with the exception of flash tubes, glass covers modelling lamps, and batteries. Products purchased for rental purposes are guaranteed for three months.
